Put the affected area in warm — not hot! — water, or warm using body heat (such as putting a frostbitten hand in your armpit)

Do not rub the area! This may damage it further

Don’t use heating pads or other artificial heat sources to warm frostbitten areas — since the tissues are numb, you might accidentally burn yourself without knowing it

The Centers for Disease Control and Prevention (CDC) state that having an “emergency cold kit” full of supplies such as extra batteries (batteries drain faster in the cold), extra blankets and/or sleeping bags, a fire extinguisher, carbon monoxide detector would help residents in affected areas remain safe.
